Description

Technical Field

[0001] This utility model relates to a pig slaughtering production line, specifically to a pig slaughtering suspension device. Background Technology

[0002] In the process of pig slaughtering, after a pig dies, its carcass needs to be suspended for slaughter and cleaning. Conventionally, hooks are used to thread the pig's two hind legs onto hooks on both sides of a suspension device, thus suspending the carcass upside down before cutting, removing the red and white parts, and washing. Existing literature CN220512071U discloses a pig slaughtering suspension device, including a side support column. A rotating motor is fixedly connected to one end of the side support column, and a suspension rotating shaft is rotatably connected to the other end of the side support column. A rotating shaft connecting buckle is fixedly connected to one end of the rotating shaft connecting buckle, and an elastic lock is engaged at one end of the rotating shaft connecting buckle. A flexible steel cable is engaged at one end of the elastic lock, and a suspension hook is engaged at one end of the flexible steel cable.

[0003] After the pig carcass is suspended, the contact force between the hook and the suspension bar increases, making it difficult to move the hook. Furthermore, after the pig carcass is hooked, the inside of the dissected carcass needs to be facing the worker or operating tools for cleaning. However, because the hook is a movable joint, its angle is difficult to adjust, and even after adjusting the angle, the hook still has room to rotate. This causes the suspended pig to rotate during the handling of its internal organs, making it difficult to lock and clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pig slaughtering suspension device that is easy to move and allows for angle adjustment and locking, thus solving the aforementioned problems.

[0005] To achieve the aforementioned purpose of easy movement and angle adjustment and locking, this utility model provides the following technical solution: a pig slaughtering hanging device, including a hook, two mounting seats fixedly installed on the outer side of the hook, a roller rotatably installed between the two mounting seats, a hinge seat fixedly installed on the side of the hook, a limit rod movably hinged to the side of the hinge seat, a fixing plate fixedly installed below the hook, a rotating sleeve movably installed on the outer side of the hook and below the fixing plate, a locking nut threaded to the bottom of the hook, and meat hooks fixedly installed on both sides of the rotating sleeve.

[0006] Preferably, an installation groove is provided on the outer side of the hook and between the fixing plate and the locking nut. A spring is provided inside the installation groove. A T-shaped clip is provided on one side of the spring. A limit ring is fitted on the outer side of the T-shaped clip and the limit ring is embedded in the opening of the installation groove.

[0007] Preferably, the inner wall of the rotating sleeve is provided with a slot and annular groove corresponding to the T-shaped clamp head. The slot and annular groove are interconnected, and there are multiple slots arranged in a ring array.

[0008] Preferably, the outer side of the roller is provided with an arc groove to facilitate its adaptation to the suspension crossbar.

[0009] Preferably, the bent end of the hook has a notch corresponding to the limiting rod, and a torsion spring is fitted on the hinge shaft where the limiting rod connects with the hinge seat to control the limiting rod to rotate downwards continuously and apply force.

[0010] Preferably, the rotating sleeve is movably engaged with the hook via a spring, a T-shaped locking head, and a locking groove.

[0011] Compared with the prior art, this utility model has the following advantages: By pushing the limiting rod upward, the hook is fitted onto the suspension crossbar, where the roller will fit against the suspension crossbar, and the entire suspension device can be moved by the roller, achieving the purpose of saving time and effort in movement; In use, the two hind legs of the pig are first suspended on the meat hooks on both sides. By opening multiple slots and ring slots on the inner wall of the rotating sleeve, the meat hook and the rotating sleeve are pushed to rotate around the vertical axis of the hook. The T-shaped clip is inserted into the corresponding slot by the spring to lock the rotating sleeve after rotation. In this process, not only is the angle of the meat hook adjusted, but the position of the meat hook after the angle is adjusted is also locked to ensure that the suspended pig will not rotate at will.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 A pig slaughtering suspension device includes a hook 1, with two mounting seats 2 fixedly installed on the outer side of the hook 1. A roller 3 is rotatably mounted between the two mounting seats 2. The outer side of the roller 3 has an arc groove to facilitate its adaptation to the suspension crossbar. The hook 1 can move on the suspension crossbar via the roller 3, making it convenient to move the pig and achieving the purpose of saving time and labor.

[0019] Please see Figure 1-2 A hinge seat 4 is fixedly installed on the side of the hook 1. A limit rod 5 is movably hinged to the side of the hinge seat 4. The bent end of the hook 1 has a notch corresponding to the limit rod 5. A torsion spring is fitted on the hinge shaft where the limit rod 5 connects to the hinge seat 4 to control the limit rod 5 to rotate downwards continuously. Pushing the limit rod 5 upwards will open the opening of the hook 1, making it easier to fit the hook 1 onto the suspension crossbar. Then, the torsion spring will cause the limit rod 5 to rotate downwards to block the opening of the hook 1.

[0020] Please see Figure 1-2 A fixing plate 6 is fixedly installed below the hook 1. A rotating sleeve 7 is movably installed on the outside of the hook 1 and below the fixing plate 6. A locking nut 8 is threaded to the bottom of the hook 1. Meat hooks 9 are fixedly installed on both sides of the rotating sleeve 7. The rotating sleeve 7 can be disassembled and installed by removing the locking nut 8.

[0021] Please see Figure 3-4 An installation groove 10 is provided on the outer side of the hook 1 and between the fixing plate 6 and the locking nut 8. A spring 11 is provided inside the installation groove 10. A T-shaped clip 12 is provided on one side of the spring 11. A limit ring 13 is fitted on the outer side of the T-shaped clip 12. The limit ring 13 is embedded in the opening of the installation groove 10.

[0022] Please see Figure 3-4 The inner wall of the rotating sleeve 7 is provided with a slot 14 and an annular groove 15 corresponding to the T-shaped locking head 12. The slots 14 and annular grooves 15 are interconnected, and there are multiple slots 14 arranged in a circular array. The rotating sleeve 7 is movably engaged with the hook 1 by the spring 11, the T-shaped locking head 12 and the slots 14.

[0023] In use, by pushing up the limit rod 5, the hook 1 is fitted onto the suspension crossbar, where the roller 3 will fit against the suspension crossbar, and the entire suspension device can be moved by the roller 3, achieving the purpose of moving in a time-saving and labor-saving manner.

[0024] In use, the pig's two hind legs are first suspended on the meat hooks 9 on both sides. Multiple slots 14 and ring grooves 15 are provided on the inner wall of the rotating sleeve 7. The meat hooks 9 and the rotating sleeve 7 are then pushed to rotate around the vertical axis of the hook 1. The spring 11 pushes the T-shaped clip 12 into the corresponding slot 14 to lock the rotating sleeve 7 after rotation. In this process, not only can the angle of the meat hooks 9 be adjusted, but the position of the meat hooks 9 after the angle is adjusted can also be locked to ensure that the suspended pig will not rotate at will.
